7 Claims. (01. 98-97) This invention relates to ventilators, and particularly to ventilators which are built into the sashes, as the lower rails of the sashes of windows, as railway cars and bus windows, which are usually made up of light sheet metal material,

and has for its object, a ventilator and sash construction or assembly, which is particularly simple and economical in construction, andin which the accumulation of dust within the sash is prevented.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. Figure 1 is a fragmentary elevation of a sash embodying my invention.

Figure 2 is a fragmentary opposite side elevation from that seen in Figure. 1.

Figure 3 is an enlarged sectional view on line 3-3, Figure 1.

a Figure 4 is an inner face View of the closure, and the adjacent platewhich retains it in position.

Figure 5 is an inner face view of the plate on the front or outer side of the sash, the screen associated therewith being also shown.

Figure 6 is an elevation of theblock which'is locatedwithin the sash member.

Figure '7 is a sectional View. on line Fig This ventilator comprises generally, a block interposed betweenand fitting between the front and rear walls of a hollow or sheet metal sash member, usually the lower railof the sash, the block having transverse ventilator openings therethrough whichare incommunication with openings in the front and rear walls of thesash member, front and rear plates overlying the front and rear walls of the sash member and having openings .alined with the openings insaid front and rear walls, one of these plates, preferably the plate on the inner or rear side of the sash, being spaced apartfrom the adjacent wall of the sash, a closure, located in the space between the last mentioned plate and the opposing wall of the sash member, and having openings movable into and out of alinement with the openings in said plate, and in the opposing wall of the sash member, the closure having. a handle on the outside of said plate, and means forclamping the plates to the sash member.

7 Some of the foregoing elements may be omitted,

and also the ventilator may be installed in any hollow frame member, regardless of whether or not the frame member is part of a sash, or of any other frame. 7

l designates generally, the sash having the 5 usual top and. bottom rails and stiles. 2 designates the bottom rail, and 3 the stiles. 4 designates the glazing.

The bottom rail is formed up of sheet metal to have opposing'front and rear walls. 5, 6 and 10 areentrant groove-l for receiving a channel 8 in which the margin of the glazing i is received. The bottom rail 2 ishereshown as provided with a buffer or weather strip ,9 of any suitable construction, this strip 9 being usually of rubber 15 having a backing I0 in the form of a sheet metal channel suitably mounted and interlocked in-the lower edge of the bottom rail. This feature in itselfy, forms no part of this invention, except that the buffer 9,, or its backing l il, constitu tes 20 the lower edge wall of the sash member on which theventilator block is mounted.

The front and rear walls of .the sash are formed with openings II and 12.; I3 is a block, usually of fibrous material, interposed between the front 25 and rear walls of the sash member 2, or between a portion of said walls, as the ventilator does not. extend the full length of the member 2, and the block preferably fills the space betweenthe front and rear walls 5, 6 with its upper edge abutting 30 against the bottompf the re-entrant groove '1, and its lower edge against thev backing H) for the buifer strip 9.- The block is formed with openings i 4 in the form of upright slots. The openings or-slots in the, front andrearwalls of the sash, 35 andfin the face platesaand the closure tobe presentlyidescribed, are of. similar shape.

l5 and H5 are-front andrear plates overlying the front and rearfwalls of the sash member-2, and formed with openings I 1 and l8'alined with 0 theopenings II and I2 of the front and rear walls of h the sash. member, one of these plates l Bbeing preferably spaced apart from the underlying wall of the sash member forming a space for the closure to be presently described.

In the illustrated embodiment of my invention, the rear or inner wall of the sash member 2 is formed with a depressed portion I!) in the bottom of which the openings I2 are formed, and this depression fits a corresponding recess-20 formed in the blockl3.

1 The plate "5 is provided with angularly bent margins 2| the edges of which abutthe bottom of the depression l9, and space the plate l6 away from the bottom of the depression. l

as by a nut 21 threading on the inner end of the stem against the inner sidef'of "the closure,

the nut working in a suitable recess or clearance 28 formed in the block 13.

A screen 29 is interposed betwee ri ithefouter I side thereof and the opposing wall of the sash plate i and the front wall of, the sash member 2.

The plates are clamped in position against the front and rear walls of the sash, member 2 by means which are self-contained with the ventilator construction, and which extend-transversely through the sash member 2 and the block l3. There are a plurality of such means suitably located as not to interfere with'the sliding of the closure, and as here shown, thejmeans are located at the corners of theplates i5, "15, and intermediate of the ends thereof,- and the closure is prcvided-wi'thslots "3B and 3! through which the fastening means extend. Each of the fastening means comprises an ordinary screw 32 and a sleeve screw 33 into which the former screw 32 threads. The screw 32 extends through one of the plates i5, it, as the plate l6 through the bottom of the depression {9 of the rear wall 6 of the sash member; and into a passage 34 in the block 13, and the sleeve screw 33 extends a through a similar opening in the plate l5 and into said passa'gefif The passages of the block 13 are preferably formed with their upper and lower Walls arouate, and also inclined downward from their inner ends toward their outer ends, so that any dust that may filter through a screen, will sift toward the lower ends of said passages, 'andto a large extent, workout thrdugh the screen;-

This ventilator is particularly advantageous in that, owing to the block #3, thedust, soot etc., is prevented from filling into the hollowsash member, and there isa minimum 'spac'e'forthe dust to accumulate, and furtherin' that theventilator is readily applied to thesash, and also-can be readily cleaned if necessary, by removing the outer plate l5, together with the screen, and cleaning out the passages H r Also, owing to'this construction, the'venti-lator can be applied substantiallyflush with the front and'rear walls-of the'sash. Also, owing to the location of the;closure the" depression in one of the walls of the sash member, the ventilator does not materially thicken the sash member. Also, owing to the mounting of the closure, it is readily operable, and owingto theblock l3 with its ventilator openings H with the'inclined upper and lower'walls, cloggingoftheclosure, or the liability of dust accumulating in the space in which the closure slides, is reduced to a minimum.
